I think its good. Looks like you have learned the use of layering in PS. If this is your first, i guarantee the rest will be real eye-candy!!
The important thing is to try
everything in photoshop, just to learn what each menu & button does. Then you can experiment all the way!
Keep 'em coming, mate!!
Edit: danlisa has a tutorial about skinning. Its really good! (danlisa learned me how to paint skins, btw.. :-)
